It seems that finally there was a conspiracy so that laptops with AMD Ryzen 4000 processors could not mount graphics cards above the Nvidia GeForce RTX 2060, and it is that although in mid-2020 it was indicated that the real reason for the limitations was that these Renoir APUs had a PCI-Express 3.0 x8 interface for GPU, which led to manufacturers indicate that there was a limited performance due to this reason.
According to the Polish website PurePC, one of the laptop manufacturers revealed the secret, indicating that there really was a secret agreement between Intel and Nvidia to guarantee that the GeForce RTX 2070 graphics cards onwards were exclusive to laptops with a processor signed by 10th Generation Intel (Comet Lake-H).
Unfortunately, the manufacturer did not reveal the terms of the agreement, but it is clear that something was there. Here’s what PurePC had to say:
“Intel and NVIDIA had an agreement signed last year, under which it was not possible to prepare laptop configurations with AMD Ryzen 4000 processors and graphics cards at the GeForce RTX 2070 level and above.”
A proof of this is that now with the AMD Ryzen 5000 you can choose up to a GeForce RTX 3080 and these Cezanne-H processors also have PCIe 3.0 lanes (x8) for the graphics card.
So theoretically we are facing with laptops that should be less powerful compared to their counterparts at Intel, but when many manufacturers have even omitted to launch models with Intel processors, it does not seem to be the case.
Dell and Razer are the only companies that have kept offering limited configurations to Intel and Nvidia.
